Recently the Department of Public Works and Highways (DPWH) announced its approval of the use of plastic waste to extend the lifetime of asphalt pavements, according to a Manila Bulletin news report.
To put things in perspective, posted below is an excerpt from the Manila Bulletin news report. Some parts in boldface…
The Department of Public Works and Highways (DPWH) has allowed the use of plastic waste to extend the lifespan of asphalt pavements and mitigate plastic pollution, which contributes to flooding in urban areas.
DPWH Secretary Manuel Bonoan has issued a directive mandating all DPWH regional offices, district engineering offices, and Unified Project Management Office clusters to incorporate shredded plastic in road construction projects.
The directive, outlined in Department Order 139, series of 2024, sets a new standard for the use of recycled materials, specifically low-density polyethylene (LDPE) plastic bags, in bituminous concrete surface courses.
Bonoan said the latest policy not only promotes recycling efforts but also improves asphalt’s resistance to deformation.
“This development is in line with the continuing efforts of the Department to support sustainable engineering and upgrade construction technology through the adoption of successful research studies,” he said.
Let me end this piece by asking you readers: What is your reaction to this recent development? Do you think this move by the DPWH will lead to breakthroughs in the years to come with regards to asphalt pavements and the mitigation of plastic pollution?
